<15% → 0%
Listed goods outside chapters 72/73/74/76 whose applicable metal is less than 15% of the article's weight owe 0% under 9903.82.03 (CBP CSMS #68253075).
kg on every claim
When 9903.82.03 is claimed, CBP expects the aggregate metal weight in kg as a second quantity on the entry line (CSMS #68253075).

Why it matters now
The data problem
Since 6 April 2026, Section 232 duties on listed steel, aluminum and copper derivatives are charged on the full customs value (CBP CSMS #68253075). Brokers still email clients spreadsheet declaration forms (example), and suppliers often can't say where their metal was smelted (example).
The deadline problem
From 14 September 2026 ACE rejects entry summaries for four copper-cable lines when copper smelt and cast countries are missing (GHY summary of CSMS #69711865). The rules changed again on 8 June 2026 (CSMS #68855869).
The money
Listed tiers run 50% (Annex I-A), 25% (I-B) and a temporary 15% total (Annex III) on full value. Illustration: on a $40,000 container of a 25%-tier product, qualifying for the 0% de minimis is a $10,000 difference, per shipment.
Sources last checked 29 September 2026. Maintained by MetalAttest. Every rule entry links to its official source, effective date and version history. Classification and filing decisions remain with the importer and its licensed customs broker. Methodology · Rules changelog · Corrections: info@metalattest.com

- Supplier attestation requests in English and Chinese for each SKU: component weights and materials, melt-and-pour / smelt-and-cast countries, mill certificates, and a typed signature with timestamp. We follow up with your suppliers for you.
- One proof pack per SKU (PDF): BOM table, the 15%-by-weight calculation, the supplier attestations and certificates (see the sample).
- A broker export (CSV/XLSX) with the metal weight in kg per line, for your broker's review.
When: kickoff call within 5 business days of your deposit. Supplier requests go out within 2 business days of kickoff. Proof packs are delivered as each supplier responds, with a target of 30 days from kickoff for all SKUs whose suppliers have answered, and a weekly status email until then.
The $99 deposit
The deposit reserves your Sprint slot and starts the kickoff. It is credited in full toward the $490, so the balance due at kickoff is $391. It is fully refundable on request until we deliver your first proof pack, and refunded automatically if we can't start your Sprint within 30 days. Details: Refund Policy.
Card payments are not live yet. Today the deposit is a commitment to pay on invoice when your Sprint starts; nothing is charged on this site.

FAQ
Do you tell me which HTS code my product is?
No. Classification of specific imports is customs business for a licensed customs broker. You give us the codes you already use; we report what the published CBP list says for those codes and collect composition facts from your suppliers.
Is exactly 15% "under" the threshold?
No. CBP's guidance says the metal must be less than 15 percent of the article's weight (CSMS #68253075). Our calculator treats 15.00% as not qualifying and warns you within 2 percentage points either side.
Which metals count toward the 15%?
Only the metal(s) the annex names for your HTS line. If a line is listed as both an aluminum and a steel derivative, aluminum + steel weights are added together; copper is not, unless the line is also listed for copper (CBP's example is 8302.10.60). Our sample proof pack shows this: only aluminum counts for 8414.59.6590.
Where does your scope data come from?
From CBP's Metals HTS List attached to CSMS #68855869 (effective 8 June 2026), versioned against the April list. Every scope page links its sources and shows when it was last verified. See our methodology.
How long does a Sprint take?
Kickoff call within 5 business days of your deposit; supplier requests go out within 2 business days of kickoff; proof packs are delivered as suppliers respond, with a target of 30 days from kickoff, and a weekly status email until then.
What if a supplier doesn't respond?
We follow up with your suppliers for you and report status weekly. If we haven't delivered a SKU's proof pack within 60 days of kickoff, we refund $19.60 for that SKU (Refund Policy).
What does my broker receive, and in which format?
A proof pack per SKU as a PDF (BOM table, calculation, attestations and certificates) and a broker export as CSV/XLSX with the metal weight in kg per line. Download the sample export (fictional data).
Who can see my supplier data?
Only MetalAttest and the service providers listed in our Privacy Policy, to deliver the service. We keep your product, supplier and pricing information confidential and do not share it with other customers (Terms, section 8).
